Engineering analysis of recovery boiler superheater corrosion
- Jansen Combustion and Boiler Technologies, Inc., Woodinville, WA (United States)
The occurrence of fire-side corrosion in kraft recovery boiler superheaters has increased in recent years due to the higher demands placed on recovery boilers. Recent research has led to new fundamental understanding of the mechanisms of corrosion in recovery boiler superheaters. However, there has been a need for development of engineering tools that combine fundamental data on superheater deposit chemistry, corrosion mechanisms, and heat transfer analysis to allow practical solutions to this problem. Factors that play an important role in superheater corrosion include superheater design and boiler operating parameters. These factors are reviewed thoroughly upon initiating an engineering analysis effort. The focal point of the superheater corrosion analysis is a comprehensive computer-based heat transfer analysis. This paper describes the engineering analysis process that has been developed and illustrates its application through three case studies.
